Leupold Base Shim Short 23mm

Leupold provides mounting shims to help users correct for poorly aligned barrels/receivers.

These can be placed inbetween a rifles receiver and the scope base/mount to help alleviate a misalignment, resulting in more upward or downward travel.

If you are running out of down travel and needing to further move your point of impact down, place a mounting shim in between your rifle’s receiver and the front base.

If you are needing more upward travel to move your point of impact up, place a mounting shim under your rear scope mount.

In some cases where a gross misalignment is present, two shims may be used.
